Sunsama organizes all the work you need to do each day in one place. It's like Trello + Google Calendar.
I love what they call "daily kanban", it's the more clear and visual way to manage a todo list for me. I like teuxdeux for that. But teuxdeux development is stopped and the product haven't moved for a long time.
daily kanban visual approach is my favorite one for todos
no mobile app, UI could be more refined
Intuitive, really easy to use productivity app.
Tasks sync with your calendar. Great for my personal tasks, and with my teams at work.
No mobile app, but I just added it to my home screenon chrome and it works great.
